London, England Application December 12, 1938, Serial No. 245,309 InGreat Britain February 1, 1938 7 Claims.

This invention relates to fittings for use with glazing bars of the kindcomprising a web having projections laterally therefrom a longitudinallyextending flange-like abutment, on one face 5 of which the glass bearsand with which it is held in engagement by a resilient clamping barwhich extends in a generally inclined direction from the point where itengages the web into contact with the other face of the glass. As a rulesuch glazing bars comprise a central web the base of which has aglass-supporting abutment on either side and in addition an outer flangelying outside each glass-supporting abutment and extending towards butnot into contact with the glass.

The object of the present invention is to provide a. convenient form ofstop to engage the end of the glass which generally extends a shortdistance beyond the bearer, purlin or other longitudinal support for theglazing bar, and further to provide a cheap and convenient means bywhich the bar can be secured to its bearer.

According to this invention the glass stop for use with a glazing bar ofthe above type comprises a substantially L-shaped strip adapted toengage the under side and end of the glazing bar and to be secured tothe bearer which supports the glazing bar. Preferably the stop comprisesa single unit, of which the shank portion, adapted to engage the underside of the glazing bar, is secured to the bearer by means of a shoe andthis shoe is so constructed that it not only engages the shank of theglass stop, so as to hold it in position on the bearer, but also engagesthe flanged lower edges of the glazing bar so as to hold it down on theshank of the stop.

In the preferred construction the shoe comprises a base plate having twocurved arms, the ends of which are provided with inturned flanges. Theshank of the stop has its longitudinal edges slotted so as to engage theupper face of the base platebetween the arms, and the arrangement issuch that after the base plate has been secured to the bearer for thebar, the shank of the stop is placed in position and the end of theglazing bar is then slid into position so that the flanged ends of thearms of the shoe engage the edges of the outer flanges at the base ofthe glazing bar. The shank of the stop is thus gripped between theflanged edge of the bar and the fixed shoe, and the upturned end of thestop will engage the web of the glazing bar when the latter is slidhome. In this way, by means of a single shoe secured to the bearer, boththe glass 55 stop and the bearer itself are locked in position.

The invention may be carried into practice in various Ways but oneconstruction according to the invention and a modification thereof areillustrated by way of example in the accompanying drawing, in whichFigure 1 is a side elevation of one construction showing the glass andbearer in cross-section,

Figure 2 is a section on the line 2-2 of Figure 1,

Figure 3 is a section on the line 3-3 of ure 1, and

Figure 4 is a similar view to Figure 2 of the modified construction.

In the construction illustrated in Figures 1, 2 and 3, the fitting isshown as applied to a glazing bar assembly of the kind forming thesubject of the present applicants copending United States of Americapatent application Serial No. 224,957, comprising a central web portionA having a flange A at its base provided with upturned riblike parts Aadapted to act as abutments on which the under surface of sheets ofglass B rest and with upturned flange-like edges A Rib-like projectionsA having grooves therein constitute anchorages for the upper edges ofresilient clamping strips which bear on the upper surfaces of the sheetsof glass B to maintain them in contact with the abutments A The parts ofthe glazing bar assembly shown are generally made by extrusion fromaluminum or other non-corrosive alloy.

In use the bar is connected within a short distance of its outer orlower end to a bearer such as the bearer D shown, the end of the barprojecting a short distance beyond the bearer and the stop according tothe invention not only serves to hold the bar from movement away fromthe bearer D but also to prevent the'bar and glass from moving in adirection parallel to the length of the bar or parallel to the length ofthe bearer.

Thus, the stop comprises a substantially L- shaped unit E having a shankportion E which lies below and parallel to the length of the glazing:bar and between the flange A and the bearer D, and an upturned endportion E against which the glass B and the end of the bar A bears, thisupturned end portion being provided with two inturned fingers E3 lyingone on each side of the web A.

As will be seen, the under side of the shank portion E is provided withribs E so as to leave a clearance space between the central portion ofthe shank E and the bearer D.

The unit E is connected to the bearer D by a shoe comprising a base Fpassing beneath the shank portion E and curved arms F the ends of whichare inturned, as shown at F to engage the edges of the parts A Theinternal shape of the arms F conforms approximately to the curvature ofthe parts A and the ribbed sides of the shank portion E of the unit Eare cut away or slotted,as shown to receive the arms F The base F issecured as by screws F to the bearer D.

It will thus be seen that the combined stop and Figshoe comprises onlytwo parts which can readily be manufactured and yet serve to connect thebar A to the bearer D in a manner preventing the bar sliding outwardsand downwards and holding the bar from movement away from or parallel tothe length of the bearer D while also acting as a stop to prevent theglass B sliding outwards and downwards.

In the modified construction illustrated in Figure 4, the form of thebar A, the L-shaped stop unit E and the manner in which these two partscooperate, is the same as in the construction shown in Figures 1, 2 and3. In the construction shown in Figure 4, however, the shoe, instead ofbeing constructed as shown in Figures 1, 2 and 3, is provided with atrough-like base F in which lies the head of a bolt F adapted to passthrough a bearer D, for example of metal, so as to secure the shoe F tothe bearer D The trough-like base is provided with a shoulder F on whichrests the part E of the unit E so that this part lies between theshoulder and the flange A of the bar A. The ribbed sides E of the part Eof the unit E are provided with slots through which the arms F of theshoe extend, as in the construction shown in Figures 1, 2 and 3, thesearms being provided with inturned edges F adapted to engage the edges ofthe parts A In this construction it will be seen that the part E of theunit E is supported by the shoe F out of contact with. the bearer D Itwill be obvious that the invention is not limited to use with glazingbars having the particular cross-section shown in the drawing and thatminor constructional features may be varied without departing from theinvention.
